In alternating current theory, the units of impedance, r.m.s. voltage and resonance frequency are respectively equal to

Answer Details

In alternating current (AC) theory, impedance is measured in ohms, r.m.s. voltage is measured in volts, and resonance frequency is measured in hertz. Impedance is the opposition to the flow of electric current in an AC circuit, similar to resistance in a DC circuit. R.m.s. voltage is the equivalent steady DC voltage that produces the same heating effect as the AC voltage. Resonance frequency is the frequency at which an AC circuit exhibits the greatest impedance. Therefore, the correct option is: ohms, volt and hertz.
